摘要
对三种主要天窗形式在重庆地区单层厂房中的实际应用状况进行了调查,测试结果证明目前大量使用的平天窗尽管具有采光效率高的优点,但其采光均匀度差、眩光重、热环境差,因此并不适合重庆地区。对性能更优的锯齿形天窗在国外现代厂房中的应用进行了介绍,通过模拟计算,对传统锯齿形天窗进行了优化设计以提高其采光效率。提出应大力研究、开发新型多功能锯齿形天窗。
This thesis investigates the practical application condition of three main kinds of skylights used in single storey factory buildings in Chongqing. The test result shows that the current widely used horizontal skylight in spite of having the advantage of high efficiency daylighting, its poor lighting uniformity, high glare rating and poor thermal environment cause it not suitable for Chongqing area. This paper introduces the application of the saw-tooth skylight used in foreign modern industrial buildings, which shows better function than others. Through a series of simulation, the tradition saw-tooth skylight is optimized to improve the lighting efficiency. And thus, we put forward to research and develop energetically on new multifunctional saw-tooth skylight.
